sum_Train={};
sum=0;
for j=1:10
while j <= 10
for i=1:10
sum_Train{j,1} = sum+results{j,1}(i,i);
end
end
end
here, result is a 10*1 cell. for each value of j, i shoild go from 1 to 10. When i is 10, the value of j should be incremented by 1 and i should start from 0 again. The result is stored in sum_Train which is 10*1 cell.

If you run the following code, you'll see that you have created an infinite loop, as j never increases inside the while loop.
for j=1:10
while j <= 10
for i=1:10
disp([i j])
end
end
end
I don't see the need for a while loop. The following should do what you described:
sum_Train={};
sum=0;
for j=1:10
for i=1:10
sum_Train{j,1} = sum+results{j,1}(i,i);
end
end

Thank you. I just solved it. Just leaving it here.
sum_Train={};
sum=0;
for j=1:length(results_Train)
while j <= length(results_Train)
for i=1:length(results_Train)
sum = sum+results_Train{j,1}(i,i);
end
sum_Train{j,1}=sum;
j=j+1;
sum=0;
end
end
